The entire contents of these provisional applications areincorporated herein by reference.

BACKGROUND OF THE INVENTION

[0002] The present invention relates to inhibiting the production oftoxic shock syndrome toxin one (TSST-1) by Staphylococcus aureus. Moreparticularly, the present invention relates to inhibiting the productionof TSST-1 in the presence of absorbent articles such as vaginal andnasal tampons, sanitary napkins, wound dressings, and diapers, byincorporating certain compounds into the absorbent articles having aninhibitory effect on Gram-positive bacteria and the production ofTSST-1.

[0003] Disposable absorbent articles for the absorption of humanexudates, such as catamenial tampons, are widely used. These disposablearticles typically have a compressed mass of absorbent material formedinto the desired shape, which is typically dictated by the intendedconsumer use. In the case of a menstrual tampon, the device is intendedto be inserted in the vaginal cavity for absorption of body fluidsgenerally discharged during a woman's menstrual period.

[0004] There exists in the female body a complex process which maintainsthe vagina and physiologically related areas in a healthy state. In afemale between the age of menarche and menopause, the normal vaginaprovides an ecosystem for a variety of microorganisms. Bacteria are thepredominant type of microorganism present in the vagina; most womenharbor about 10⁹ bacteria per gram of vaginal fluid. The bacterial floraof the vagina is comprised of both aerobic and anaerobic bacteria. Themore commonly isolated bacteria are Lactobacillus species,Corynebacteria, Gardnerella vaginalis, Staphylococcus species,Peptococcus species, aerobic and anaerobic Streptococcus species, andBacteroides species. Other microorganisms that have been isolated fromthe vagina on occasion include yeast (Candida albicans), protozoa(Trichomonas vaginalis), mycoplasma (Mycoplasma hominis), chlamydia(Chlamydia trachomatis), and viruses (Herpes simplex). These latterorganisms are generally associated with vaginitis or venereal disease,although they may be present in low numbers without causing symptoms.

[0005] Physiological, social, and idiosyncratic factors effect thequantity and species of bacteria present in the vagina. Physiologicalfactors include age, day of the menstrual cycle, and pregnancy. Forexample, vaginal flora present in the vagina throughout the menstrualcycle can include lactobacilli, corynebacterium, ureaplasma, andmycoplasma. Social and idiosyncratic factors include method of birthcontrol, sexual practices, systemic disease (e.g., diabetes), andmedications.

[0006] Bacterial proteins and metabolic products produced in the vaginacan effect other microorganisms and the human host. For example, thevagina between menstrual periods is mildly acidic having a pH rangingfrom about 3.8 to about 4.5. This pH range is generally considered themost favorable condition for the maintenance of normal flora. At thatpH, the vagina normally harbors numerous species of microorganisms in abalanced ecology, playing a beneficial role in providing protection andresistance to infection and makes the vagina inhospitable to somespecies of bacteria such as Staphylococcus aureus (S. aureus). The lowpH is a consequence of the growth of lactobacilli and their productionof acidic products. Microorganisms in the vagina can also produceantimicrobial compounds such as hydrogen peroxide and bactericidesdirected at other bacterial species. One example is the lactocins,bacteriocin-like products of lactobacilli directed against other speciesof lactobacilli.

[0007] Some microbial products produced in the vagina may negativelyaffect the human host. For example, S. aureus is a bacteria thatcommonly colonizes human skin and mucous membranes. It causes disease inhumans through invasion or through the production of toxic proteins. Onesuch disease is toxic shock syndrome (TSS), caused by toxic shocksyndrome toxin-1 (TSST-1) and other similar toxins. When absorbed intothe blood stream, TSST-1 produces TSS in non-immune humans. An increasedincidence of TSS is associated with growth of S. aureus in the presenceof tampons, such as those used in nasal packing or as catamenialdevices.

[0008]S. aureus is found in the vagina of approximately 16% of healthywomen of menstrual age. Approximately 25% of the S. aureus isolated fromthe vagina are found to produce TSST-1. TSST-1 has been identified ascausing TSS in humans.

[0009] Symptoms of TSS generally include fever, diarrhea, vomiting and arash followed by a rapid drop in blood pressure. Multiple organ failureoccurs in approximately 6% of those who contract the disease. S. aureusdoes not initiate TSS as a result of the invasion of the microorganisminto the vaginal cavity. Instead as S. aureus grows and multiplies, itcan produce TSST-1. Only after entering the bloodstream does TSST-1toxin act systemically and produce the symptoms attributed to TSS.

[0010] Menstrual fluid has a pH of about 7.3. During menses, the pH ofthe vagina moves toward neutral and can become slightly alkaline. Thischange permits microorganisms whose growth is inhibited by an acidicenvironment the opportunity to proliferate. For example, S. aureus ismore frequently isolated from vaginal swabs during menstruation thanfrom swabs collected between menstrual periods.

[0011] When S. aureus is present in an area of the human body thatharbors a normal microbial population such as the vagina, it may bedifficult to eradicate the S. aureus bacteria without harming members ofthe normal microbial flora required for a healthy vagina. Typically,antibiotics that kill S. aureus are not an option for use in catamenialproducts because of their effect on the normal vaginal microbial floraand their propensity to stimulate toxin production if all of the S.aureus are not killed. An alternative to eradication is technologydesigned to prevent or substantially reduce the bacteria's ability toproduce toxins.

[0012] There have been numerous attempts to reduce or eliminatepathogenic microorganisms and menstrually occurring TSS by incorporatinginto a tampon pledget one or more biostatic, biocidal, and/ordetoxifying compounds. For example, L-ascorbic acid has been applied toa menstrual tampon to detoxify toxin found in the vagina. Others haveincorporated monoesters and diesters of polyhydric aliphatic alcohols,such as glycerol monolaurate, as biocidal compounds (see, e.g., U.S.Pat. No. 5,679,369). Still others have introduced other non-ionicsurfactants, such as alkyl ethers, alkyl amines, and alkyl amides asdetoxifying compounds (see, e.g., U.S. Pat. Nos. 5,685,872, 5,618,554,and 5,612,045).

[0013] Despite the aforementioned attempts, there continues to be a needfor compounds that will effectively inhibit the production of TSST-1from Gram positive bacteria, and maintain activity even in the presenceof the enzymes lipase and esterase which can have adverse effects onpotency and which may also be present in the vagina. Further, it isdesirable that the detoxifying compounds useful in the inhibition of theproduction of TSST-1 be substantially non-harmful to the natural florafound in the vaginal area.

[0087] The present invention is illustrated by the following exampleswhich are merely for the purpose of illustration and are not to beregarded as limiting the scope of the invention or manner in which itmay be practiced.

EXAMPLE 1

[0088] In this Example, the effect of various test compounds on thegrowth of S. aureus and the production of TSST-1 was determined. Thetest compound, in the desired concentration (expressed inmicrograms/milliliter) was placed in 10 mL of a growth medium in asterile, 50 mL conical polypropylene tube (Sarstedt, Inc. Newton, N.C.).

[0089] The growth medium was prepared by dissolving 37 grams of brainheart infusion broth (BHI) (Difco Laboratories, Cockeysville, Md.) in880 mL of distilled water and sterilizing the broth according to themanufacturer's instructions. The BHI was supplemented with fetal bovineserum (FBS) (100 mL) (Sigma Chemical Company, St. Louis, Mo.).Hexahydrate of magnesium chloride (0.021 M, 10 mL) (Sigma ChemicalCompany, St. Louis, Mo.) was added to the BHI-FBS mixture. Finally,L-glutamine (0.027 M, 10 mL) (Sigma Chemical Company, St. Louis, Mo.)was added to the mixture.

[0090] Compounds to be tested included hexachlorophene, triclosan and4-hydroxydiphenyl methane. Test compounds were received as solids. Thesolids were dissolved in methanol, spectrophotometric grade (SigmaChemical Company, St. Louis, Mo.) at a concentration that permitted theaddition of 200 microliters of the solution to 10 mL of growth mediumfor the highest concentration tested. Each test compound that wasdissolved in methanol was added to the growth medium in the amountnecessary to obtain the desired final concentration.

[0091] In preparation for inoculation of the tubes of growth mediumcontaining the test compounds, an inoculating broth was prepared asfollows: S. aureus (MN8) was streaked onto a tryptic soy agar plate(TSA; Difco Laboratories Cockeysville, Md.) and incubated at 35° C. Thetest organism was obtained from Dr. Pat Schlievert, Department ofMicrobiology, University of Minnesota Medical School, Minneapolis, Minn.After 24 hours of incubation three to five individual colonies werepicked with a sterile inoculating loop and used to inoculate 10 mL ofgrowth medium. The tube of inoculated growth medium was incubated at 35°C. in atmospheric air. After 24 hours of incubation, the culture wasremoved from the incubator and mixed well on a S/P brand vortex mixer. Asecond tube containing 10 mL of the growth medium was inoculated with0.5 mL of the above-described 24 hour old culture and incubated at 35°C. in atmospheric air. After 24 hours of incubation the culture wasremoved from the incubator and mixed well on a S/P brand vortex mixer.The optical density of the culture fluid was determined in a microplatereader (Bio-Tek Instruments, Model EL309, Winooski, Vt.). The amount ofinoculum necessary to give 5×10⁶ CFU/mL in 10 mL of growth medium wasdetermined using a standard curve.

[0092] This Example included tubes of growth medium with varyingconcentrations of test compounds, tubes of growth medium without testcompounds (control) and tubes of growth medium with 20-400 microlitersof methanol (control). Each tube was inoculated with the amount ofinoculum determined as described above. The tubes were capped with foamplugs (Identi-plug plastic foam plugs, Jaece Industries purchased fromVWR Scientific Products, South Plainfield, N.J.). The tubes wereincubated at 35° C. in atmospheric air containing 5% by volume CO₂.After 24 hours of incubation the tubes were removed from the incubatorand the optical density (600 nm) of the culture fluid was determined andthe culture fluid was assayed for the number of colony forming units(CFU) of S. aureus using standard plate count procedures. The remainingculture fluid was prepared for the analysis of TSST-1 as follows: theculture fluid was centrifuged at 2500 rpm at about 2-10° C. for 15minutes. The supernatant was filter sterilized through an Autovial 5syringeless filter, 0.2 micrometer pore size (Whatman, Inc., CliftonN.J.). The resulting fluid was frozen at −70° C. in a Fisherbrand 12×75milliliter polystyrene culture tube.

[0093] The amount of TSST-1 per mL was determined by a non-competitive,sandwich enzyme-linked immunoabsorbent assay (ELISA). Samples of theculture fluid and the TSST-1 reference standard were assayed intriplicate. The method employed was as follows: four reagents, TSST-1(#TT-606), rabbit polyclonal anti-TSST-1 IgG (LTI-101), rabbitpolyclonal anti-TSST-1 IgG conjugated to horseradish peroxidase(LTC-101), and normal rabbit serum (NRS) certified anti-TSST-1 free(NRS-10) were purchased from Toxin Technology (Sarasota, Fla.). A 10microgram/milliliter solution of the polyclonal rabbit anti-TSST-1 IgGwas prepared in phosphate buffered saline (PBS) (pH 7.4). The PBS wasprepared from 0.016 molar NaH₂PO₄, 0.004 molar NaH₂PO₄—H₂O, 0.003 molarKCl and 0.137 molar NaCl, (Sigma Chemical Company, St. Louis, Mo.). Onehundred microliters of the polyclonal rabbit anti-TSST-1 IgG solutionwas pipetted into the inner wells of polystyrene microplates(Nunc-Denmark, Catalogue Number 439454). The plates were covered andincubated at room temperature overnight. Unbound anti-toxin was removedby draining until dry. TSST-1 was diluted to 10 nanograms/milliliter inPBS with phosphate buffered saline (pH 7.4) containing 0.05% (vol/vol)Tween-20 (PBS-Tween) (Sigma Chemical Company, St. Louis, Mo.) and 1% NRS(vol/vol) and incubated at 4° C. overnight. Test samples were combinedwith 1% NRS (vol/vol) and incubated at 4° C. overnight.

[0094] The plates were treated with 100 microliters of a 1% (wt/vol)solution of the sodium salt of casein in PBS (Sigma Chemical Company,St. Louis, Mo.), covered and incubated at 35° C. for one hour. UnboundBSA was removed by 3 washes with PBS-Tween. TSST-1 reference standard(10 nanograms/milliliter) treated with NRS, test samples treated withNRS, and reagent controls were pipetted in 200 microliter volumes totheir respective wells on the first and seventh columns of the plate.One hundred microliters of PBS-Tween was added to the remaining wells.The TSST-1 reference standard and test samples were then seriallydiluted 6 times in the PBS-Tween by transferring 100 microliters fromwell-to-well. The samples were mixed prior to transfer by repeatedaspiration and expression. This was followed by incubation for 1.5 hoursat 35° C. and five washes with PBS-T and three washes with distilledwater to remove unbound toxin.

[0095] The rabbit polyclonal anti-TSST-1 IgG conjugated to horseradishperoxidase wash diluted according to manufacturer's instructions and 50microliters was added to each microtiter well, except well A-1, theconjugate control well. The plates were covered and incubated at 35° C.for one hour.

[0096] Following incubation the plates were washed five times inPBS-Tween and three times with distilled water. Following the washes,the wells were treated with 100 microliters of horseradish peroxidasesubstrate buffer consisting of 5 milligrams of o-phenylenediamine and 5microliters of 30% hydrogen peroxide in 11 mL of citrate buffer (pH5.5). The citrate buffer was prepared from 0.012 M anhydrous citric acidand 0.026 M dibasic sodium phosphate. The plates were incubated for 15minutes at 35° C. The reaction was stopped by the addition of 50microliters of a 5% sulfuric acid solution. The intensity of the colorreaction in each well was evaluated using the BioTek Model EL309microplate reader (OD 490 nanometers). TSST-1 concentrations in the testsamples were determined from the reference toxin regression equationderived during each assay procedure. The efficacy of the compounds ininhibiting the production of TSST-1 is shown in Table I below.

[0097] In accordance with the present invention, the data in Table 1shows that S. aureus (MN8), when compared to the control, producedsignificantly less TSST-1 in the presence of the hexachlorophene andtriclosan compounds. At the concentration tested, these compoundsreduced the amount of toxin produce by 68% to 88%. Although4-hydroxydiphenyl-methane did reduce the toxin production by about 24%,it lacks the chlorine and hydroxyl groups that have been shown tostabilize triclosan in the active site of the enzyme/NAD complex.

The mutants were selected by plating overnight growth ofS. aureus FRI-1169 in growth medium onto tryptic soy agar platescontaining 5 micrograms/milliliter triclosan. The effect of triclosanwas determined by placing a range of concentrations, expressed inmicrograms/milliliter, in 10 mL of growth medium as set forth inExample 1. The samples were then tested and evaluated utilizing theprocedure set forth in Example 1.
